High-Density MT Ferrule Optical Cable Assemblies Extend Space and Cost
Savings Up to 72 Fibers
With the addition of the High Density MT (HDMT) ferrule optical cable assembly line, Molex further strengthens
its position as a leader in optical backplane and front panel interconnect solutions. These cable assemblies offer
multiple space-saving options on the front panel by using the 72-ber MT ferrule in the industry standard MTP*
connector, as well as high-density panel-mount Array connectors. In addition, by incorporating the HDMT
ferrule in the HBMT backplane interconnect, customers can benet from the highest-density blind-mate
interface in the industry.
These HDMT ferrules extend the capabilities of traditional MT-style connectors beyond 12 and 24 bers, making
congurations up to 72 bers possible. Molex has developed termination and polishing capabilities achieving
insertion-loss levels that are comparable to those of 24-ber terminations.
This signicant increase in bers in a single connector offers considerable space savings, along with reduced
installation time and cost. Molex is developing exible ruggedized trunk cabling solutions that utilize the HDMT
ferrules, which are designed to reduce ber installation costs in central ofces and data center applications. Low
prole, high ber count trunk cables streamline the routing of the trunk cables and reduce the number of ber
pulls.
